Starlab is a software package for simulating the evolution of dense
stellar systems and analyzing the resultant data. It is a collection
of loosely coupled programs (``tools'') linked at the level of the
UNIX operating system. The tools share a common data structure and can
be combined in arbitrarily complex ways to study the dynamics of star
clusters and galactic nuclei.

AMUSE provides a homogeneous interface to a variety of
packages that enable complex astrophysical simulations across
different physical domains, such as stellar evolution,
hydrodynamics, and gravitational dynamics. The package
including all our developed scripts is publicly available at
github
